The CPDVR083V3UA-HF 3.3V unidirectional, four-line ESD protection diode array meets the immunity requirements of IEC 61000-4-2 level 4 (±20kV air, ±15kV contact discharge). Measuring 2.1 mm x 1.6 mm x 0.525 mm, the device promises to simplify board layout and reduce board space by as much as 70% when compared to four single-line discrete devices. The CPDVR083V3UA-HF is recommended for flow-through design on PCB layouts, where the traces enter one side of the device and exit the other. Comchip Technology Corp., Fremont, CA. (510) 657-8671.
